Abstract (en)
[origin: WO2020188016A1] The invention relates to a heating member (30) for a vehicle exhaust gas purifying device comprising an electrically conductive peripheral frame (42) having an inner edge (46), a central support (64) arranged substantially at the geometric centre (G) of the inner edge (46), and a perforated heating grid (72) formed of a plurality of elongate heating elements (74) each having first and second ends (75, 76) opposite one another, the first end (75) being linked to the peripheral frame (42) and the second end (76) being linked to the central support (64). Each elongate heating element (74) occupies a respective angular sector (77) of the heating grid (72) and is arranged in zigzag manner inside this angular sector (77) so as to form a succession of strands (82, 83) connected by nodes (88) and being linked by said nodes (88) to the elongate heating elements (74) occupying the neighbouring angular sectors (77).
